y y IMPROVEMENT aN HORSE HAY-RAKES.

Specification forming part of Letters Patent l94,0l11, dated August 7, 1877'; application led August 1,1877. y

To all whom it may conccm':

Be it known that I, JOHN H. THOMAs, of Springfield, county of Clarke, State of Ohio, have invented certain new andV useful Improvements in Horse-Rakes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this speciiication, in which- Figure 1 is a perspective view of a horsei latter are raised for that purpose.

It consists in providing a cleaner or cleanerrake, suspended by hinged or pivoted rods or arms, with friction-rollers arranged eccentrically to or below the cleaner-head, and traveling over one or more of the rake-teeth as the latter are raised and loweredthereby obviating all scraping action between the rake-teeth and cleaner.

It further consists in the combination, with the swinging cleaner, provided with frictionrollers traveling or rolling on the rake-teeth, as described, of guiding-brackets for preventing lateral play of the cleaner and insuring the proper relation of the rollers to the teeth over which they are intended to move, and

in providing said brackets with lugs or stops,

which hold the cleaner and its rollers above -and free from the rake-teeth when the latter are down in position for gathering their load,

y all as hereinafter explained.

drivers seat E and the lifting-lever F,

through which the attendant controls the action of the rake, are mounted, said parts being constructed and arranged in any usual or preferred manner.

Upon the thill or draft frame are secured two backwardly-inclined standards, Gr Gr, so arranged'that their rear upper ends overhang the rake-head A, and to said upper ends pendent brackets h h (see Fig. 4.) are secured by bolts passing through horizontal flanges h1, or in any other convenient manner.

The brackets h have perforated ears h2, in which are secured the angular ends lof pendent rods or links 7c k, the lower ends of which pass throughand are secured to the cleaner rake-head K, the arrangement being such as to permit the cleaner to swing freely with the rods k la in following or conforming to the movement of the rake-teeth C.

The pendent brackets h are expanded in width, and the rods lo are secured to, and vibrate back and forth by the side of, and in close proximity with, the vertical faces of said brackets, and being placed Von opposite sides thereof lateral movement of the swinging rods and of the cleaner-rake is prevented. The brackets h are provided at their lower ends with horizontal spurs h", which project under the rods k, serving as stops for limiting the downward movement of said rods and for holdingv the cleaner-head K above and clear from the rake-teeth (l when the latter are down at work.. The cleaner-head is provided with cleanerteeth k' having any usual or preferred form andV arrangement for stripping or cleaning the rake-teeth G when the latter are raised to dischargs their load, and is further provided 4with rollers m m, arranged eccentrically to the axial center of said head, or in such relation thereto as to project below the head and arranged in vertical planes coincident with those of the rake-teeth C C over which they are to move when the rake-teeth are raised or lowered. These rollers may be two or more in number, and may be secured directly to the bar or head K, one at each end, upon eccentrically-arranged pivots, as shown in the bottom View, Fig. 3, or they -may be mounted in short pendent brackets, and at points intermediate between,.the ,endsff of the cleaner-head. By preference they will be arranged in pairs for balancing the head', andin such manner that both ends of the head will be acted upon simultaneously when the rake-teeth are raised or lowered. These rollers, as statedi, are arrangedin the same ver'ti` cal planes with the rake-teeth, and rest upon and move in contact therewith* holding the cleaner-head raised above and free from the rake-teeth, and obviating the scraping action and friction consequent upon allowing the tion may be further insured,. if desiredl, by l the; em ploymentv of grooved rollers;
